Microduct-tube winder, double station winder, processing system for empty plastics microduct tubes and method for winding up such tubes

Abstract

The invention relates to a microduct-tube winder (5) for winding up extruded empty plastics microduct tubes having an outside diameter of about 2 to about 20 mm, having a reel (8) which is rotatable about a rotation axis (16) and has a core (9) arranged between two radially projecting flanges (10), the tube being windable on said core (9), and having a tube guiding device (6), via which the tube is fed to the reel (8), wherein a first transfer point is provided on the tube guiding device (6), the tube losing contact with the tube guiding device (6) at said first transfer point in the operating state of the microduct-tube winder (5), and wherein provision is made of a second transfer point, assigned to the reel, the tube coming into contact with the core (9) or a tube layer wound onto the latter at said second transfer point, wherein the tube guiding device (6) is movable in a transverse plane of the reel (8) and the reel (8) is movable in the direction of its rotation axis (16) such that in the operating state the winding angle (a) at the second transfer point always remains the same. The invention also relates to a double station winder (1) having two such microduct-tube winders (5), to a processing system having a microduct-tube winder (5), to a manufacturing system having an extrusion apparatus and a processing system and to a method for winding up an empty plastics tube.

Description

technical field [0001] The present invention relates to a microduct pipe winding machine for winding extruded microduct-plastic empty pipes having an outer diameter of about 2 mm to about 20 mm, said microduct pipe winding machine having a an axis rotating reel having a core disposed between two radially projecting flanges onto which the pipe can be wound, and said micropipe pipe winding machine having pipe guides through The pipe guide conveys the pipe to the reel, wherein there is a first delivery point on the pipe guide at which the pipe loses contact with the pipe guide in the operating state of the micropipe pipe winder, There is also a second delivery point assigned to the reel at which the tube comes into contact with the core or the tube layer wound on the core. Microduct pipe winding machines can also be referred to as winding devices, by means of which microducts—plastic empty pipes—can be wound onto reels.

Problems solved by technology

However, such accumulators often have the disadvantage that the winder or a downstream-connected belt puller pulls the tube through the accumulator and thus the tube is subjected to elongation, which is undesirable since this impairs the accuracy of the tube

[0015] Satisfactory results may not be obtained at high speeds for very small micropipeline tubes even with modifications to existing winders
